Another snippet of literature (following this one) that I think about regularly - this time, from Excession by the late great Iain M. Banks. The Culture Series describes an interstellar post-scarcity civilization, wherein most of the administration and governance is carried out by hyper-advanced AIs called Minds, and biological beings (who live on terraformed planets, on megastructures like Bishop Rings, or aboard planet-sized space-faring Ships) are free to pursue leisure and self-improvement. Basically, Fully Automated Luxury Gay Space Communism.
